CRUST BREAKER.

Application filed November 15, 1926. Serial No. 148,452.

This invention has reference to .a device designed for use in connectionwith disk cultivators, and aims to -provide novel means operatingbetween adjacent disks of a cultivator for breaking the ground surfaceor crust between the disks, during the l harrowing operation.

An important object of the invention is to provide means for regulating'the .pres sure on the device, thereby adapting it for use in breakingthe ground surface when the ground surface has become exceptionallyhard. n n

A still further object of the invention is the provision of means toadjust the device with respect t0 the cultivator frame, so that thepressure directed to the crust breaker, may be regulated with a degreeof accuracy, and the device may be used in connection with cultivatorsof various types.

l/Vith the foregoing and other objectsin view which kwill appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction` hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimedtwithout departing from the spirit of theinvention.

Referring to the drawing:

Figure l is a longitudinal sectional view through the device showing thesame as supported on a cultivator frame.

Figure 2 is a plan view of the device.

Referring tothe drawing 1n detail, the reference character 5 designatescultivator beams to which the disks 6 are secured in the usual and Wellknown manner.

rlhe device forming the essence of the present invention is designed foruse in connection with a cultivator and more particularly with acultivator of a disk type, the same being shown as positioned in such away that it contacts with the ground sur face between the disks to crushor break the same.

The device includes a pair of arms 7 that are provided with a pluralityof openings 8 to receive the bolt 9, which bolt also passes through theeye 10 formed at the lower end of the bar 11, the eye 10 being shown aspositioned between the arms 7 This bar 11 has a rearwardly extended endportion 12 provided with an opening through which the rod 13 passes, therod 13 being provided with a threaded portion 14 to accommodate the nut15, so that the rod 1S may be moved. through the opening for purposes tobe hereinafter more fully described.

As shown by Figure 2, arms 7 have outwardly and rearwardly extended endportions 16 formed with openings to receive the shaft 17 on which theroller 18 operates, the roller being provided with a plurality of teeth19 adapted to dig into the ground surface between the disks of thecultivator and which have been partially loosened by the cultivatordisks.

The shaft 17 also passes through the downwardly extended portions of theframe 2O to which the rod .13 has connection, as at 21, with the resultthat the roller 18 will be held against lateral movement.

Openings 22 are formed in the bar 11 and are designed to receive thebolts 23 that pass through openings in the bar 24 to clamp the device tothe beam 5 of the cultivator.

Since the bar 11 is rigidly secured yto a cultivator beam, it will beseen that as the nut 15 is operated, the rod is elevated and the spring13 placed under tension. When the proper tension has been placed on thespring, the bar 11 may be. lowered or elevated to meet the requirementso that greater or less pressure is directed to the roller to adapt itfor its particular work.

From the foregoing it will be seen that due to this construction, theeiiciency of the usual cultivator employed in cultivating beets isgreatly increased. Y

It might be further stated that this device may also be usedv inconnection with disk harrows, or the like for conditioning the groundsurface for planting.

I claim:

1. In a device of the character described, a frame, said frame includinga vertical bar having a plurality of spaced openings, means extendingthrough the openings for securing the bar to a cultivator frame, saidbar including a rearwardly extended portion having an opening, a rodextending through the opening, a roller frame supported at the lower endof the rod, a spring surrounding the rod, and positioned between therearwardly extended end of the bar and roller frame to exert a pressureon the roller frame, and a roller having teeth, operating in the rollerframe.
